The third London Bridge attacker has been named as 22-year-old Youssef Zaghba, a Moroccan-Italian man.
Pakistan-born Khuram Butt, 27, and Rachid Redouane, 30, both from Barking were the other two attackers.
Two more victims have been been named – Australian nurse Kirsty Boden, 28, and French national Alexandre Pigeard, 27, died in Saturday night’s attack.
They were among seven people killed – 48 were also injured – before the three attackers were shot dead by police.
Zaghba, Butt and Redouane drove a hired van into pedestrians on London Bridge at 21:58 BST before stabbing people in the area around Borough Market.
Armed officers killed all three within eight minutes of receiving a 999 call.
The Metropolitan Police said Butt had been subject to an investigation in 2015, but there had been no suggestion this attack was being planned.
